“…As compared with the TOF ratio measured mechanomyographically using a force transducer-the gold standard of the neuromuscular monitoring device, the TOF ratio assessed acceleromyographically is prone to be higher when the TOF ratio evaluated mechanomyographically is more than 0.7 [28]. Additionally, Kopman [29] reported that even when recovery from neuromuscular block was significant, T1/control assessed electromyographically tended to return to only 0.8.…”

“…On the other hand, accelerographic TOFR is comparable to mechanical TOFR in the mechanical TOFR range of 0 to 0.70. 11 However, accelerographic TOFR tends to be higher than mechanical TOFR when mechanical TOFR > 0.70. 11 This finding would also concur with the present results that the accelerographic TOFR in the P-TOF group was higher than the mechanical TOFR in the S-TOF group.…”

It has been shown that a mechanical TOFR > 0.9 correlates well with signs of adequate recovery of neuromuscular blockade.…”

P Pu ur rp po os se e: : To study accelerographic monitoring of neuromuscular blockade over the vastus medialis muscle in anesthetized patients in the prone position.M Me et th ho od ds s: : Sixty adult patients were divided into four groups of 15: prone (P)-post-tetanic count (PTC), P-train-of-four (TOF), supine (S)-PTC or S-TOF group. In the P-PTC and P-TOF groups, the muscular branch of the femoral nerve was stimulated and the movement of the vastus medialis muscle was measured accelerographically. In the S-PTC and S-TOF groups, the depth of neuromuscular blockade was assessed mechanically at the thumb. After administration of vecuronium 0.1 mg·kg -1 , TOF stimuli were delivered every 20 sec in all groups. Onset of neuromuscular blockade (time from vecuronium to the minimum level of T1 (first response of TOF) was compared between the P-PTC or P-TOF group and S-PTC or S-TOF group. Recoveries of PTC and those of TOF were compared between the P-PTC and S-PTC groups and P-TOF and S-TOF groups, respectively. R Re es su ul lt ts s: : Onset of neuromuscular blockade in the P-PTC or P-TOF group was shorter than in the S-PTC or S-TOF group (132 ± 43 vs 233 ± 40 sec, mean ± SD, P < 0.001). Recoveries of PTC in the P-PTC and S-PTC groups followed a similar time course. Recoveries of T1/control in the P-TOF and S-TOF groups were also comparable. In contrast, train-of-four ratio (T4/T1, TOFR) in the P-TOF group was higher than in the S-TOF group 60-120 min after vecuronium (P < 0.05).C Co on nc cl lu us si io on ns s: : The degree of neuromuscular blockade can be assessed accelerographically over the vastus medialis muscle even when patients are in the prone position. When evaluated accelerographically over the vastus medialis muscle, onset of neuromuscular blockade is quicker and TOFR is higher than that assessed at the thumb.Objectif : Étudier la mesure accélérographique du blocage neuromusculaire du muscle vaste interne chez des patients anesthésiés en décubitus ventral. moyenne ± l'écart type, P < 0,001 Méthode : Soixante adultes ont été répartis en quatre groupes de 15 : compte post-tétanique en décubitus ventral (CPT-V), train-de-quatre-V (TDQ-V), CPT-D en décubitus dorsal ou TDQ-D. Dans les groupes CPT-V et TDQ-V, la branche musculaire du nerf fémoral a été stimulée et le mouvement du muscle vaste interne mesuré par accélérographie. Dans les groupes CPT-D et TDQ-D, la profondeur du blocage neuromusculaire a été évaluée mécaniquement au pouce. Après l'administration de 0,1 mg·kg -1 de vécuronium, des stimuli en TDQ ont été administrés à toutes les 20 sec chez tous les patients. L'installation du bloc, c'est-à-dire le temps entre l'administration du vécuronium et le niveau minimal de T1 (première réponse au TDQ), a été comparée entre les groupes CPT-V ou TDQ-V et les groupes CPT-D et TDQ-D. La récupération du CPT et celle du TDQ ont été respectivement comparées entre CPT-V et CPT-D et entre TDQ-V et TDQ-D. Résultats: L'installation du bloc dans le groupe CPT-V ou TDQ-V a été plus courte que dans le groupe

“…Die mit der Akzeleromyographie erhobenen Parameter verhalten sich ähnlich wie die mittels Mechanomyographie oder Elektromyographie gemessenen Werte, allerdings ist eine gewisse "Überschätzung" erkennbar [12,22]. Wohlwissend um die technischen Besonderheiten dieser Meß-methode, scheint die Akzeleromyographie, sowohl nach eigenen klinischen Erfahrungen als auch im Einvernehmen mit den Ergebnissen in der einschlägigen Literatur, für den klinischen Alltag ausreichend sensitiv und zuverlässig zu sein [11,21,33].…”
